Since you bisected this down to a commit from Arjan, it might
help to cc him.

Adding him and lkml.

> cpuidle: fix the menu governor to boost IO performance

> The reason for a reworked governor is that there have been serious

> To show this I'm sure Andrew wants to see benchmark results:

> In various power benchmark measurements, no degredation was found by our
> measurement&diagnostics team. Obviously a small percentage more power was
> used in the "fio" benchmark, due to the much higher performance.

> While it would be a novel idea to describe the new algorithm in this
> commit message, I cheaped out and described it in comments in the code
> instead.
